UNITED STATES SIDNEY HJSHORT, OF CLEVELAND, OHIO, ASSIGNOR TO THE SHORTELEO- PATENT OFFICE.

TRIO RAILWAY COMPANY, OF SAME PLACE.

CROSS-OVER vFO Fi TROLLEY-LINES.

SPECIFICATION forming part of Letters Patent No. 447,208, dated February24, 1891.

Application filed October 22, 1890- To all whom it may concern.- Be itknown that I, SIDNEY H. SHORT, of Cleveland, in the county of Ouyahogaand State of Ohio, have invented certain new and useful Improvements inCross-Overs for Trolley-Lines of Electric Railways; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to the means for'carrying one trolley-line orsupply-conductor of an]- tioned line, which is carried over the bridge,

while those on said first-mentioned or bridge line pass along the bridgeand across the notch. The present invention has more particularreference to cross-overs of this description; but each of theimprovements constituting said invention is included for all the uses orapplications to which it may be adapted.

One at least of such improvements is applicable to trolley-linesotherwise than in cross overs-as, for example, in frogs or switches.

In accordance with the present invention the cross-over is composed ofan arch, preferably of metal, provided with means for retaining theconductor in arched position that is to say, with a curve at thecross-over upward above its normal leveland with one or moretrack-pieces, preferably of insulating material, on which thetrolleyruns in making the crossing. By this improvement the hearing for thetrolley at the crossing may be brought more in linewith the conductor oneither side thereof. Further, by employinga metal arch in connectionwith a track-piece or track-pieces of Wood or insulating materialstrength is secured without sacrificing efficiency. Preferably the meansfor retaining the conductor in arched position consist Serial No.368,994; (No model.)

of clips, which inclose the conductor and are fastened to the arch.Further, the bottom of the arch is made wider than the conductor and isgrooved to receive the same, the clips passing through slots in thearch. The track piece or pieces are preferably placed between dependingears or flanges on the arch and secured by bolts or pins passing throughthe ears or flanges and the interposed track-piece, A clip incloses theconductor and the adjacent end of the track-piece.

The cross-over is' provided with a holder for the insulating-support ofthe transverse trolley wire or conductor, and this holder is in thepresent invention formed bya divided socket, one half formed in asuitable part of the arch or an attachment thereto-such as a bracket-andthe other constituted by a removable piece. The insulating-support isheld in the socket. The said holderis best formed in or by a lateral armor bracket, so that the insulating-support for the transversetrolley-wire is at one side of the cross-over.

The invention extends to the cross-over provided with the holder for thetransverse trolley-wire in a lateral arm or bracket irrespective of theform of the holder, as Well as when said holder is formed by.a dividedsocket.

Another feature belonging to the present invention consists in aninsulating track-piece of wood in two or more thicknesses or laminaesecured together with their grain in different directions, the tread ortrack-bearing being formed on the edge of the track-piece by the edgesof one or more of the thicknesses or laminae. Preferably this laminatedtrackpiece increases in width above the bearin surface for the trolleys,which surface is formed bythe edge of one of the thicknesses or laminae.A solid bearing is thus given for the trolleys to travel on, while at{the same,

view of a crossover constructed in accordance with the invention,showing the line-conductors in place. Fig. II is .a plan of the same.Fig. III is a cross-section on line iii of Fig. I. Fig. IV is a sectionon line in of Fig. I. Fig. V is a side view ofa part of the track-piece,broken away in places to exhibit its laminated structure; and Fig. VI isa side view, on a smaller scale, of a double-wire crossover constructedin accordance with the invention, the clips being omitted, as well asthe conductors and the insulatingsupports of the transverse conductors.

The conductor Act the trolley-line in which the cross-over is placed issecured to the under side of the brass arch B by means of the clips2,which hold it in an upwardly bent or arched position. The archB isprovided with a groove 3 underneath to receive the conductor A and haslateral flanges 4, between which the groove 3 is formed. The clips 2pass through openings 5 in these flanges and their ends are bolted orriveted to the fiatfacedlumps 6 on the sides of the web 7 of the arch.

The track-piece O of the cross-over is placed under the conductor B withits upper part be tween the depending ears 8 of the arch A, and is theresecured by bolts or pins 9. The clips 2 at the ends of the track-pieceshave toes 2',whioh extend under the said ends and assist in supportingthe said track-piece as well as protecting the joint between it and theconductor B.

The track-piece shown (see Figs. 1V and V) consists of three thicknessesor laminae of wood secured together by cement, with the grain in thelayers running in different directions. The middle lamina extends beyondthe others, and its under edge constitutes the tread or bearing-surface10 of the track-piece, which is thickened above by the additionallaminae.

The track-piece C is notched at 11 for the passage of the transversetrolley-wire or conductor D, whose insulating-support E E, consisting ofthe support E and insulator E, is held in the holder F. constituted bythe bracket projecting from the side of the arch A above the notch 11.This bracket may be-cast on or otherwise made in one piece with thearch, as shown in Figs. I, II, and III, or may be bolted or otherwisefastened thereto, as shown in Fi VI. here there are more than onetransverse conductor, a corresponding number of notches 11 may be madein the trackpiece 0.

The insulator Eof the support E is held in a socket formed by thestationary part 12 on the arch and the removable piece 13, which isbolted thereto. A rib 14 on the inside of the socket engagesacorresponding groove on the outside of the insulator.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The cross over composed of an arch, means for securing the conductoror trolley wire in an arched position thereon, and a separatetrack-piece secured within the arch, substantially as described.
